The demutation processes in the isle forest massives (on the example of sfr gorki leninsky and kanevsky park)

The object of investigation: the isle forest massives,the forest phytocenoses, populations. The purpose of the work: the development of the main methodical approaches to the analysis of the demutation processes in the forests, and revealation of the principal laws of restoration of the population structure and species variety in the model massives. On the base of presentations of the new forest paradigm and investigation of the history of the nature utilization,the methodological approaches to the analysis of the demutation changes in the forest cenoses have been developed, the evaluation of the successive state of the forests has been performed, the prognosis of its development has been given. Suggested has been the base for the organization of the population monitoring and compiling the prognosis for the development of the concrete forest massives, suggested and approved have been the methods on restoration of window mosaic of renovation and species variation in the model forest massives. The results of the investigation have been used in the forest arrangements of the Kanevsky park reserve (1987) and State Forest Reserve "Gorki Leninsky" (1991)Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio

THE MECHANICAL PHENOMENA IN THE PROCESSES OF SOLIDIFICATION

Used have been 10 epoxide systems. The purpose of the work: to establish the laws of the shrinkage defect-formation with the solidification under the restrained conditions, near to the isochoric ones. The phenomenon of the shrinkage defect-formation with the isothermal solidification under the restrained conditions has been detected, the new methods of investigation of the shrinkage defect-formation have been developed, the new laws of this phenomenon have been established. The connection with the relaxation transitions in the course of solidification has been shown; the theoretical models of the shrinkage defect-formation (including those in the polymer compostites) have been developed. The recommendations on optimization of the mode of solidification have been given.Available from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
